Application filed April 3,

kota, have invented certain new and useful.

Improvements in a Hayraclr-Sill djuster, oi which the Vfollowing is a specification.

The present invention relates to a hay rack sill adjuster vand has for its principal object to provide a device for attaching the sills to a wagon bolster in fixed relation to the post ot the bolster and so that the distance between the sills may be varied if desired and then fixed against accidental displacement.

Another important object of the invention is to provide a device ot this nature which is simple and etli'cient in construction, reliable in operation, inexpensiveto manufacture, durable, and well Aadapted to the purpose for which it is designed.

With the above Aand numerous other objects in view as will appear as the description progresses, the invention resides in certain novel features of construction7 and in the combination and arrangement ot parts as will be hereinafter more t'ully described and claimed.

For the purpose ot illustrating my invention, I have shown in the accompanying drawing that form thereof which is at present preferred by me7 since the same will give in practice satisfactory and reliable resultsv`v although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.y

with the usual end post 2 rising therefrom. The hay rack sills 3 arefdisposed transversely ot' the wagon bolster y1 and are held inplace .by my appliance. Therek are two of these appliances one for each sill Each Aappliance includes a pair ot clamps :A and B. The clamp Ajconsists ot' a bodyplate 5 having bolts 6 rising from its ends and a bar 7 rising trom one ot its Vmid portion. This bar 7 is provided atits ends with the transversely'extending lugs 8 and at its intermediate portion with the transversely extending lugs 9. The lugs S and 9 extend inthe same direction and areadapted to be disposed along the sides of the post 2. This bar 7 is also provided with a series of apertures 10. A pair of aws 11 are adjust able on the body plate 5. Each jaw 11 includes a body 13 having a longitudinally extending slot 14 for receiving one of the bolts 6. At one end ot the body portion 13 a downward extension-15 is provided terminating in a series of offset teeth16 extending substantially parallel with the body 13. At the other end ot the body 13 there is disposedan apertured lip 17 rising' at .Y right angles from the body 13 and in an opposite direction from the extensionl.

There are two jaws 11 on the body plate 5 and they are locked in place by the thumb nuts 18 engaged with the bolts 6. A' bolt 19 passes through the apertured lips 17 which are disposed adjacent each other so that they may be drawn toward each other by a thumb nut 2OV on the bolt 19. The teeth 16 of the extensions 15 engage the sides ot the bolster' 1 as is illustrated to advantage in Figure 2. Q

The clamp B consists ofl a body plate 5 having bolts Gfrising from its ends and aV bar 7 i rising trom one side ot' its intermediate portion and provided with a series of apertures 10.- Thus tar this clamp is identical' with Vthe clamp A just described and includes the same jaw structure indicated generally at 11. A sill engaging member 22 is constructed .with a plate body having an elongated longitudinal-ly extending slot 23 therein and an overhanging hook extension 2feterminating in a' series ot'teeth 25 Jfor engagement with the upper edge o. a sill 3. This engaging member 22 is mount ed on the bar 7 by means of a bolt 26 which passes through the upper aperture 10. Y Y

A bracing member@ 's disposed between the bars 7 and 7 vand may be adjusted Vin sesses ya large variety ot usages and oit 5 course the presentusuage has merely been lgiven by way of example. l Having thus described my invention what f1- claim -as new is fl@ Anappliance of the class described in cludingv a pair of clamps, a pair ot bars, one 'rising'- from each clamp; engaging means on thebars,v and adjustable bracingv means dis- :posed 'betweenk the bars inthe manner.y and for the purpose specified.

.12; An v-appliance of ythe class described including afrpair of clamps, a pair of bars, l"one: rising' from each clamp, lugs extending #from the side edgesfofone bar, and an engageable member adjustable on the other bar and includingafhooked extension having a .toothed terminal,V `and l bracing means Y between'the bars. f

f3. Anf' appliance of the class described including a 'pair of clamps, each 'clamp' confsistingr of a? bodyplate, a pairof jaws ad- TjuStahleaOnA the bodyf plate, and a standard risingf from the intermediate; portion fot the body plate, engagingmeans on the standards and bracing means between the standards.

i4. 'An 'applianceof the class described tor holding hay rack sills upon wagon holsters including a clamp consisting of a .plate body, bolts rising from the ends ot the plate body, jaws engaging said bolts, nuts engaging said `bolts 'for holding` said jaws plate, an engaging member adjustable Vertically on the standard and including a hooked extensionterminating in a series of teeth.

5. An appliance of the class described including' a clamp for engagement with-a wagon bolster. a standard extending'rom the clamp and including a hay ra'clsill engaging member. and adjustable means for bracing the standardl in 'relation to the post of the bolster.
